Have someone tried to clone YouTube with Joomla? And I mean every feature of YouTube (apart from the video player and great transcoding capability): the user system with community functions (essentially: subscribtions, comments, ratings, internal messaging system, profile pages with comments and video lists, playlists). I am aware that there are plenty of components for Joomla that may in a right combination result in a YouTube clone. But to find the right components and to configure them in the right way is quite a challenge. The community builder component alone requires a lot of configuration! Is there a pre-configured image/db-dump of Joomla with all the necessary modules/plug-ins/components?
